Do Classical Physics Still Have Unsolved Problems?

In summary, the Wikipedia article lists one unsolved problem in classical mechanics, specifically regarding singular trajectories in the Newtonian N-body problem. The question of whether the set of initial conditions for near-collisions leading to infinite speed in finite time has measure zero is still open for N > 4. However, the list may not be considered definitive as many items could fit into multiple categories and solutions may exist for practical purposes.

First, a lot of the items in that list would rightly fit into multiple categories. Turbulence, for example, could certainly fit under classical physics but is listed under condensed matter physics.

Second, a Wikipedia list should not be considered definitive by any stretch of the imagination.

I know, which is why I asked the question - was curious.

Charged point particles are still not well defined, but that problem is solved at least partiall and "for all practical purposes" by QED.
 

FAQ: Do Classical Physics Still Have Unsolved Problems?

What are the major unsolved problems in classical physics?

The major unsolved problems in classical physics include the origin of mass in the universe, the nature of dark matter and dark energy, the existence of singularities in black holes, the unification of general relativity and quantum mechanics, and the arrow of time.

Why are these problems considered unsolved?

These problems are considered unsolved because they do not have a complete and universally accepted explanation within the framework of classical physics. While there have been many theories and attempts to solve these problems, none have been proven to be the definitive answer.

How have scientists attempted to solve these problems?

Scientists have used a variety of approaches to try and solve these problems, including mathematical models, experimental observations, and theoretical frameworks. Some of the most well-known attempts include the Standard Model of particle physics, the theory of relativity, and quantum field theory.

What impact would solving these problems have on our understanding of the universe?

Solving these problems would have a significant impact on our understanding of the universe. It could lead to a more complete and unified theory of physics, potentially allowing us to better understand the fundamental laws that govern the universe and make more accurate predictions about its behavior.

Are there any potential solutions to these problems on the horizon?

While there is no definitive solution to these problems yet, there are ongoing efforts and research in various fields of physics that could potentially lead to a breakthrough. Some of these include experiments at the Large Hadron Collider, advancements in string theory, and the search for new particles and forces beyond the Standard Model.
